How does to take to fully recover after open heart surgery on an infant?

Varies: As with any surgery, this varies. It would depend on the exact surgery required as well as whether there are any complciations. Usually it would involve one to two weeks in the hospital and four to eight weeks at home. It also depends on what you mean by "recovery." the chest could be sore for a much longer period for instance.

Baby hearts: Typically, kids recover more quickly after heart surgery than adults. It's important, though, to consider what exactly has been fixed with the operation. There are some surgeries on kids that require multiple steps to complete. What that means is that the child may not be completely repaired after the first procedure.

Stages: "full" recovery takes months. But i typically think of this in stages. The child is usually hospitalized ~10-14 days. Then the major portion of the recovery is complete by ~2 months (i.e. Home for ~6-8 weeks). But it will take another few months for the sternum to completely heal, etc.
